What about, "If a vendor supports the on-line forum I visit" and interacts with customers, and has a great reputation I tend to order from them ?!
btw, maybe down the road, we will implement here a real "Vendor" rating system. Vendor's could be rated on several aspects of how they conduct business. I'm sure that this would be handy for people sitting on the fence, or trying to decide who to buy from. I'm not sure if there are any legal ramification to this though.
